Question

Show transcribed image textA message signal with power PMn = 1/2 and whose frequency is less than 1000 Hz modulates the earner c(t) = 10-3 cos(2 pi fct). The modulation scheme is conventional AM with a modulation index of 0.5. The channel noise is additive white with power spectral density of 10-12 W/Hz. At the receiver, the signal is processed as shown in the Figure (a) below. The frequency response of the bandpass noise limiting filter is shown in figure (b) below.
